Not sure what specific tool you are referring to that you are using to create 3D Objects or to Elevate Objects - but the Snaps at the base of the screen in V5 has a Surface Vertex Snap Option that you may have turned off - if that is on when you have an Elevation Field - when the field is selected you can click on any Surface Vertex to create the Elevation Value.

I have tried Properties, Create Line, Create Point, Edit Line (Vertical) and they all work as expected

Let me know if it is as simple as the Snap not being enabled - if not please tell me tye command(s) that you are using that are not working this way

The only other thing along the same vein, I can snap to the vertices now, however the near point used to work along the lines of the wireframe of the surface. Any small setting change to get that one working again aswell?
